Thank you, plagiarism. There is a new development in a high-profile serial murder case. Police are investigating whether a man in custody on a weapons charge has a connection to the series of shockings killings in Alexandria, Virginia. His resemblance to the man police are looking for is uncanny. Take a look and ABC's Linzie Janis is here with the details. They really do look alike in the sketches, Linzie. Good morning. These murders inside -- they're hoping police have their man but authorities are stressing that this is still an unongoing investigation and that the people of Alexandria should continue to be aware of their personal safety. Alexandria police tell ABC news while investigating the three brutal murders haunting the suburban D.C. Community, anonymous tips led them to this man, Charles severance, a convicted felon he was arrested in West Virginia fry for weapons violations. They're trying to put together the pieces of the puss toll directly tie him to the murder of one of these three individuals. Reporter: In a news release Alexandria police stress it is premature to name him as the only possible suspect. But many here in this D.C. Suburb are pointing out that severance's booking photo bears a striking resemblance to this sketch the man responsible for the shooting death of Ruthanne Lodato. In February Lodato was gunned down after opening her door to a strange man. Her caretaker was also shot but survived. The caretaker may end up being a direct eyewitness to the case. Reporter: In fact, it was the caretaker's description that helped police create this sketch. In a February news conference, Alexandria police linked Lodato's murdering to the slay of Ron Kirby, a local transportation official and the 2003 of a police chief's wife, Nancy Dunning. The similars and unusual nature of all three shootings occurring in Alexandria require the police department to consider the possibility that all the cases are linked together. Everybody is talking about it. I mean, that's the only thing that it's really affecting everybody and nobody knows the facts. Reporter: Well, here are the reasons police think that the murders are connected. The victims were all involved in the community, all were shot in their hopes during the day and within two miles of each other. Finally, the bullets used in all three murders are similar. Dan and bianna, the man that they have in custody, severance, one interesting thing about him. He ran for mayor twice in the community so he's known to the community. Well, if this is closure at least the residents can sleep better. But again police stressing still not have connected him. Linzie, thank you. I'm 11% happier drinking out of this mug. We are going to shift gears
